Very Computer

I'm having problems with my Samba / internet connectivity.  I have the
following setup:

Router (192.168.0.1) --- eth0 (192.168.0.3) - eth1 (192.168.1.1) ---
Windows workgroup (192.168.1.2-10)

Once I'd set IP addresses on the Windows PCs (I'm using static IP
addresses), using the default FC7 IPtables setup, the Windows PCs
could see the internet, but not see the Samba share I'd created.
Adding 2 rules to the IPtables manually, on the command line:

-I INPUT -i eth1 -p UDP -m multiport --dports 137, 138, 631 -j ACCEPT
-I INPUT -i eth1 -p TCP -m multiport --dports 135, 139, 445, 631 -j
ACCEPT

solved this problem.  However, adding the following lines to /etc/
sysconfig/iptables file:

-A RH-Firewall-1-INPUT -p udp -m udp --dport 137 -j ACCEPT
-A RH-Firewall-1-INPUT -p udp -m udp --dport 138 -j ACCEPT
-A RH-Firewall-1-INPUT -m state --state NEW -m tcp -p tcp --dport 139
-
j ACCEPT
-A RH-Firewall-1-INPUT -m state --state NEW -m tcp -p tcp --dport 445
-
j ACCEPT

I've attempted various combinations of adding port 631 to the rules
file but nothing seem to work.  If anyone can help me with what the
correct rules should be, I'd be most grateful.

Thanks,
Chris
